Using a hand lens and a hammer, you smash a mineral and notice it breaks into tiny, flat pieces. What can you conclude from your observations?

• The mineral is soft.

• The mineral is hard.

• The mineral has cleavage.

• The mineral does not have cleavage.

How can you describe a mineral that has a measure of 8 on the hardness scale, sparkles, and breaks into square chunks?

• It is soft, metallic, and has cleavage.

• It is hard, metallic, and has cleavage.

• It is hard, non-metallic, and has cleavage.

• It is hard, metallic, and does not have cleavage.

What tools can be used to make observations of the sparkles of a mineral?

• Hammer

• Streak plate

• Flashlight

• Steel nail

Howard is performing a streak test to determine the color of various minerals he found. Which statement best describes why Howard should compare his observations with others?

• He could meet a scientist with his same interest in minerals.

• He might find a new mineral that is unknown to scientists.

• It will help him identify differences in observations.

• It will let others know not to repeat his experiments.

Eugenie and Tony both investigated the properties of minerals they found while on a walk. Take a look at the table with their observations. What was similar between the two sets of observations

• The mineral was red and had luster.

• The mineral was metallic and had luster.

• The mineral was metallic and had cleavage.

• The mineral was non-metallic and had luster.
